Giant infrared intensity of the Peierls mode at the neutral-ionic phase transition
Luca Del Freo, Anna Painelli, Zoltan G. Soos
We present exact diagonalization results on a modified Peierls-Hubbard model for the neutral-ionic phase transition. The ground state potential energy surface and the infrared inte…

Vibronic contributions to resonant NLO responses: two-photon absorption in push-pull chromophores
Anna Painelli, Luca Del Freo, Francesca Terenziani
Two-photon absorption (TPA) spectra of push-pull chromophores are described in terms of a two-state model accounting for electron-vibration coupling. Vibrations have two main effec…
